Application filed Janualy'l?, 1923. Serial No. 613,298.V

To all whom t may concern Be it known that I, ALPI-Ions H. Gris, a citizen of the United States, residing at Chicago, in the county of Cook, State ot Illinois, have invented certain new and useful Improvements in Lubricating Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new .and useful improvements in lubricating devices and particularly to shaft lubricating devices of the wick-feed type. Y

One object of the invention is to provide a lubricator by means of which all of the oil is delivered from -the container regardless of the wear on the service end et' the wick.

Another object is to provide a lubricator of this character wherein it is unnecessary to renew the entire oil feeding wick as a result of wear at the service end.

Another object is to provide an oil cup of the type mentioned whereinv it will be unnecessary to remove the cup `for refilling.

In the drawing:

Figure 1 is al vertical sectional view through a steering knuckle of an automobile, and through the oil cup ot the invention.

Figure 2 is a view of the wicks, the main portions thereof being broken away.

Referring particularly to the accompanying drawing in which it has been elected to illustrate the invention as used in connection with the steering knucklel of 4an automobile, 10 represents a portion ofone of the stub axles of .an automobile, and 11 the vertical spindle or shaft.

In one side of the stub axle 10 there is formed a transverse opening 13, leading into the longitudinal bore 14, of the axle 10, andv being internally threaded to receive the externally threaded nipple 15, carried by the upper end of the side of the oil cup or container 16. The upper end of the oil cup 16 is provided with a spring closed cover 17. In the end of the nipple 15, adjacent the side of the cup 16 there is formed a circumferential shoulder 18, which defines the opening 19, leading into the interior of the cu A wici, designated as a whole by the numeral 20, has its horizontal portion 21 lspindle by the wick 2l) under of the spring.

25, formedon the u per end of the portionV 22, whereby a flexible joint is produced.

Vwhich permits the vertical portion 2 2 to remain in its vertical position in the cup,

while the horizontal portion slides within the nipple. The outer end of the portionV 21 is disposed a short distance inwardly of `the outer end of the nipple 16, and adjacent the opening 1301:' the stub axle. Disposed in the bore of the nipple, in encircling relation to the adjacent end portion of the wick,

is a coil spring 26 one end of saidspring being secured to the adjacent end of thel wich and the other end ofthe spring having bearing' upon the shoulder `18. In the end of thenipple there is disposed a cylindrical felt member 27, the outer end of whichv bears against -the spindle 11, to supply oil thereto. The inner end of the telt member is formed with a socket 28 to receive the adjacent end of the wickV 20, and is urged against the the influence Oil will be drawn upwardly through the wick 20, by capillary action, l and be delivered into the bore of the nipple, from whence it will be absorbed by the felt -member 27, and iinally distributed onto the spindle 11. 1

IVhen the parts are rst assembled, the length of the felt member 27 is such that the spring 26 is compressed within the nipple, and as the outer or service end et the felt member wearsA away, this spring will advance the felt member to maintain contact thereof with the spindle. Attention is called to the fact that as the felt memberl advances, the wick 2O moves bodily acrossv the' oil cup, the lower end of said wick maintaining its contact with the bottom of the cup so that all of the oil will be drawn from the cup, no matter to what stage of wear the felt member has reached. Thus oil will be delivered from the cup, to the last drop. n Y

It will be noted that with this type of lubricator, the cup does not need to be removed for the purpose of refilling.

Again, when'the service end of the wick wears completely away, it is'not necessary Yto remove the main wick, but simply requires `the removall of the cup from the axle,

and the replacement of the worn felt meinAA ber 2 7, by a new one. j j

By reason of the wire core of the main wick 2 0, said vwick is maintained in lthe same position or shape, at all times, so that when the new member 27-is pressed into the nipple, the wick will not crowd around the shoulder, as would be the case were an ord1- nary flexible wick used.

- Furthermore,were the felt member 2.7 not usedthe wire core of the wick wouldl Y nipple andztheother vertically Within the contact with the article to be lubricated.

While I have shown a Wick having a wire core, I wishit understood that a one-piece, felt, or fabric wick may be used with equal facility and eiectiveness. 1 What is claimed is vIl. A lubricating device including a lubricant container, ka pair of wicks within the.

container having their adjacent ends loosely connected, an independent and separable. lubricating element carried byone otthc Wicks, and means .for urging. the same against an element to be lubricated. v 2.. A lubricating device including a lubricant-container, a pair4 oi wicks within the container having their adjacent ends loosely connected, and an independentand separable lubricating velement carried by oneior"A the v wicks.

8. Thecombination with an oil-cup yliaving a laterallydirected nipple. provided` Witha shoulder at its inner end, oi' a wick having one portionk disposed vertically in the cup and its other lportion -flexibly connected with the vertical portion and dis- 1 posed horizontally Within .the nipple, a second wick in the nipple and bearing against the adjacent end ofthe said' horizontal portion, and a spring rwithin the nipple andl connected with/the horizontal portion and 4. The combination with an oil-cup havinga laterally directedV nipple, of a wicky comprising flexibly .connected legs, one of the legs being disposedchorizontally within the said nipple, the other of the legs being disposed verticallywithinthe cupa second 'cal leg of lthe first Wick in constant close proximity to the bottom oli-the cup.

. 5. The combination with an oil-cup having a laterally directed nipple,of a .spring urgedl wick'liaving flexibly-connected legs, one of which is disposed horizontally in the cup, and ak replaceable service-end for the horizontal leg comprising a felt body provided lwith a socket receivingthe adjacent' Y end of said leg.

6. In a lubricating device, the combinay tionwith a lubricant vcontainer, havin@` a .laterally directed nipple, of; a pair of flex? pendent and replaceablelubricating element wcarried by the Wick within the nipple.

.7. A lubricating device comprising a cup having a lateral outlet duct, a wire cored wick disposed horizontallyv within the duct and having an end within the cup bent upon itself to form an eye, a second wire cored wick loosely connected with said eye and depending vertically vwithin kthe cup, and ay spring mounted within the outlet duct and l connected with vthe horizontal' wickto cause longitudinal movement thereof, and transversel bodily movement of the vertical` Wick within the cup. e: Y f 8. In. a lubricating device, the combination with a lubricant` container having :i

laterally kdii'ectedpiiipple *provided*y with a n shoulderaty its inner end, of va pair offwicks having their adjacent ends loosely connected. Y'

one wick being positioned withinA the container and the other beingpositioned within 'the nipple, a replaceable lubricating element carried by the wick Within the nipple, and

Aspring ,means Within the nipple and bearing at yone end against the shoulder, for urging the replaceable element against an eleinentto be lubricated. 1

In testimony whereof, I ture.
